ENGINEERING Flexi
CONTROL SYSTEM
Flexi series units are provided with a proprietary RD4 control
system by ATREA. This control system meets all requirements for
demand-controlled ventilation.
The RD4 control system has an integrated web server. As
a result Flexi series units can be run from the Internet via
devices such as laptops and smart phones.
Moreover, the control system is fitted in the units already in
production during which everything is also inspected. DUPLEX-S
Flexi units are therefore supplied as plug-n-play systems.
All this increases the ease of installation and reduces costs.
Various functions of the RD4 control system:
Constant flow – An option to fit sensors for constant flow
control.
Constant pressure – An optional accessory for constant
pressure control.
CO 2
sensors, relative humidity sensors and air quality
sensors – An option to set the intensity of ventilation automatically
based on those parameters. Reduces operating
costs.
Versatility – The orientation of the unit, that is, which is the
supply and which is the extractor fan, is determined simply
by setting the parameter in the control system.
Modbus TCP – Communication with a higher-ranking
system for BMS.
Parameter setting by the user – Including setting weekly
programmes for ventilation, heating and cooling modes.
Immediate manual override settings for more convenience
to the user as well as weekly programme control.
A ventilation run-down and delay time option – Thanks
to the external inputs.
Combined heating and preheating
